技术领域
本发明涉及2-亚胺-9-芳基取代的邻菲啰啉与其铁络合物的制备方法及其应用。具体的讲是以2,9-二氯邻菲啰啉与芳基硼酸进行偶联反应制备9-芳基取代的邻菲啰啉,经过后续的偶联、水解、缩合等反应最终得到2-亚胺-9-芳基取代的邻菲啰啉,将其与氯化亚铁进行络合反应,可以制备相应的邻菲啰啉铁络合物。该邻菲啰啉铁络合物能够催化1,3-共轭二烯与硅烷的硅氢化反应,得到高烯丙基硅化合物,表现出很高的活性和选择性,特别是对于芳基取代的1,3-共轭二烯的硅氢化,给出优于其它已知金属催化剂的1,2-反马氏加成的选择性,具有很好的应用前景。
背景技术
有机硅化合物是含有C-Si键的化合物统称,由其组成的有机硅材料具有表面张力低、粘温系数小、无毒无味且生理惰性等优点,被广泛应用于航空航天、建筑、化工、食品和医疗等诸多领域[Ojima,I.In The Chemistry of Organic Silicon Compounds,Patai,S.,Rappoport,Z.,Eds.;Wiley:Chichester,U.K.,1989;Vol.1;Chapter 25.],因此对有机硅化合物的合成和应用研究具有重要意义。烯烃的硅氢化反应是最重要、最基础的C-Si成键反应之一,具有100%的原子经济性,为有机硅化合物的合成提供了一种高效的方法。相比于金属试剂与硅试剂的偶联反应来构筑C-Si键的方法,烯烃硅氢化反应具有条件温和、操作简单、原子利用率高等优势,并且可以从大宗工业原料烯烃和硅烷出发合成有机硅化合物,为有机硅化学及有机硅材料的高速发展提供了有力支撑[(1)Marciniec,B.Coord.Chem.Rev.2005,249,2374.(2)Marciniec,B.In Hydrosilylation,AComprehensive Review on Recent Advances,Eds.;Spring,2009.(3)Du,X.Y.;Huang,Z.ACS Catal.2017,7,1227.]。
1,3-共轭二烯作为一类重要的烯烃,由于具有共轭的两个碳碳双键,过渡金属催化其硅氢化反应时存在多种配位和插入方式,导致区域、立体和化学选择性多样,难以调控。
由于过渡金属催化1,3-共轭二烯的硅氢化反应时,容易形成较为稳定的π-烯丙基金属中间体,进而生成1,4-加成产物。目前人们已经发展出很多基于Fe、Co、Ni、Pt、Pd等金属的催化剂,都能实现1,3-共轭二烯的1,4-加成选择性硅氢化[(1)Lappert,M.F.;Nile,T.A.;Takahashi,S.J.Organomet.Chem.1974,72,425.(2)Ohmura,H.;Matsuhashi,H.;Tanaka,M.;Kuroboshi,M.;Hiyama,T.;Hatanaka,Y.;Coda,K.-I.J.Organomet.Chem.1995,499,167.(3)Han,J.W.;Hayashi,T.Tetrahedron:Asymmetry 2010,21,2193.(4)Hilt,G.;Luers,S.;Schmidt,F.Synthesis.2003,634.(5)Wu,J.Y.;Stanzi,B.N.;Ritter,T.J.Am.Chem.Soc.2010,132,13214.]。相对而言,1,3-共轭二烯的催化1,2-加成选择性硅氢化反应更具挑战性,长期缺乏有效的催化剂。直到2014年,Ritter等人发展出环烷基膦双核铂催化剂,利用大位阻配体使金属不容易产生金属-π烯丙基中间体,成功抑制了1,4-加成选择性,才实现了简单1,3-共轭二烯的1,2-加成选择性硅氢化反应[Parker,S.E.;Borgel,J.;Ritter,T.J.Am.Chem.Soc.2014,136,4857],但是这类铂催化剂作用的底物类型十分受限。近年来,人们发展出一系列双齿N,N-配体与铁、钴等丰产金属的络合物,实现了1-芳基1,3-共轭二烯的1,2-马氏加成选择性的硅氢化反应[(1)Hu,M.Y.;He,Q.;Fan,S.J.;Wang,Z.C.;Liu,L.Y.;Mu,Y.J.;Peng,Q.;Zhu,S.F.Nat.Commun.2018,9,221.(2)Wen,H.A.;Wang,K.;Zhang,Y.L.;Liu,G.X.;Huang,Z.ACS Catal.2019,9,1612.]。而三齿N,N,N-配体和钴的络合物则可催化1-烷基1,3-共轭二烯的1,2-加成的硅氢化反应[Raya,B.;Jing,S.;Balasanthiran,V.;RajanBabu,T.V.ACS Catal.2017,7,2275.]。然而,迄今1-芳基1,3-共轭二烯类的1,2-反马氏加成选择性控制仅停留在中等水平[(1)Greenhalgh,M.;Frank,D.J.;Thomas,S.P.Adv.Synth.Catal.2014,356,584.(2)Raya,B.;Jing,S.;Balasanthiran,V.;RajanBabu,T.V.ACS Catal.2017,7,2275.]。
因此发展用于1,3-共轭二烯硅氢化反应的新型过渡金属催化剂,特别是基于丰产金属的催化剂,克服已知催化剂存在的缺点,实现文献中还不能很好控制的1,2-反马氏加成选择性,是本领域研究的重点之一。
